To all whom# ma/ z/ concern.'-

Be it known that I, JEssE G. VINCENT, a citizen of the United States,and resident of Detroit, Wayne County, State of Michigan,

have invented certain new and useful Improvements in Hydrocarbon Motors,of which the following is 'a specification.

This application is a division of my Patent No. 1,265,145, dated May`7,1918, and

it relates to hydrocarbon motors and particularly to means forlubricating the vae rious bearings of the motor.

One of the objects of the invention is to produce a simple oiling systemin which most of the pipes or conduits are arranged within the motoritself.

Another object of the invention is to employ the m'otor valve operatingor cam shaft as a conduit and a distributor for the lubrieating oil tothe various rcrank shaft and connecting rod bearings.

Anotherl .object ofthe invention to utilize the oil pressure systemagainst the end of the valve operating shaft to reslst the 2lil endthrust thereon, due to the valve being driven through helical gears.

Other objects of the invention will appear from the-followingdescription taken in connection with the drawings which form a part' ofthis specification, and in which:

` Fig. 1 is a sideelevation and part lol'lgitudinal sectional view of ahydrocarbon m` tor embodying the invention; I

Fig. 2 is an enlarged section lof thefront end of the valve operatingshaft; and

Fig. 3 isa transverse section substantially 011 the line 3-3 of Fig. 2.

Referring to the drawings, 10 indicates the crank case or supportingbase of a 'hydro-A carbon motor having abottom. cover 11, and

va rearward extension 12, .forming a casing for the `fly wheel 13. Themotor cylinders` 14v-are shown' as' Cast in pairs and mounted n on 'thecrank case, the motor shown com- Qne of the valves is shown at 15,operated bythe valve lifter16 and the spring 17. .To the fly wheel 13 issecured the motor AcrankA shaft 18,. having in the present i11- ycase10, the bearings bein stance, seven main bearings 1 9, which are formedin transverse webs 20 of the crank supported and secured to the webs bybearing blocks 21.

Also mounted in the seven bearings 27 of the webs 20, is avalveoperating shaft or cam shaft 28, which extends parallel to the crankshaft and is driven therefrom through hellcal gears 29-30, thusproducing end thrust on cam shaft 28, which may be taken in part by theplain thrust bearing 31.

throughout its length, thus forming a conduit for the lubricating oilthat is supplied from there tllroughthe holes 33 tothe in` teriorfof theshaft. Thus the hollow shaft is kept constantlyl full ofoil underpressure, and as its rear end 36 is opposed by anabutment 37 the oilpressure within the shaft tends to force the latter forwardly againstThe cam shaft 28 is shown as drilled the end thrust exerted upon it bythe gears I 29-30. Thus considerable of the end thrust is taken from theplain bearing 31 and the n rotating shaft floats in itsbearings.

In case of the oil pressure within the cam shaft overcoming the rearwardend thrust of the helical gearsfthe forward end thrust of the shaft maybe taken by a spring plunger 38, sliding in a thimble 39, secured in theAforward end of the cam shaft. This plunger is backed by a spring 40,secured in the thlmble by a removable plug 41, and an internal flange 42retains the plunger in the thimble until the bolt or, abutment 43 in theforward -cover 44 is secured in place. This bolt 43 i's preferablyadjustable, to give the required vtension to the 'spring 40, and isprovided pipe or conduit 49 leads from the lower conterior of thecrankshaft suitable pipe 52b necting rod bearing to the piston pinbearing (not shown) at the upper end of the rod. Also at its main.bearings the crank shaft has radial holes 50 which are adapted toregister with the respective conduits 46 so that the oil supplied underpressure to the said conduits 46 will' enter the crank shaft mainbearings and be distributed to them, and .any excess of oil will passfrom the into the connecting rod bearings and to they squeezed outthrough all of these bearings during the operation of the motor and willbe thrust from the various revolving and reciprocating parts andcollected at the bottom of the crank case in the sump formed bythebottom cover 11. It has been shown above how oil is Supplied totheinterior of the cam shaft 28 under pressure, and upon reference to Figs.

, 1 and 3 it will be seen that the cam shaft is lprovided with aradialhole 52 at each of its earlngs, gles to each other, the presentlcam shaft havmg seven bearings, and they holesv being preferablyarranged equi-distant, .so that each of these holes 52 'registers'during each revolution of the camshaft with its respect1ve conduit 46 sothat oil under pressure is distributed by means of the cam shaft 28 tothe various conduits in succession, not more than one conduit beingsupplied at a given time, thus maintaining the pressure in the'distributing cam shaft.

A pressure gauge 5221 is connected' byta with the space between the`rear end 36 `Vof the cam shaft and the abutment 37,. This d l theeXtreme rear end of the` cam shaftv so thatfthe minimum pressure withinthe cam shaft is the lpressure registered.

' In ig. 11 the oil pump 53 is shown in elevatlon as Secured to the sideof the crank case 10.as by'bolts '54. A pipe 55 leads from the bottom ofthe crank case or sump to the intal'e side of the pump and the pipe 34hereinabove described leads from the pump to the forward bearing 27 vofthe cam shaft where the oil is carried to the interior of the cam shaftby the groove 32V and holes 33. Another pipe 56 leads from the deliveryend of the pump to any desired auxiliary system, not shown in thedrawings.

Having thus described my invention, what I claim and desire to secure byLetters Patent 1s:

2. Ina motor, the combination with the crank shaft, a valve operatingshaft, and driving gears between said shafts creating end thrust on thevalve shaft, of an abutment at one endv of said shaft, means for feedingoil under -pressure between said rabutment and said shaftend to resistsaid end thrust, and a spring thrust bearing at the other endofsaid'shaft to take up the eX- cess of thrust over that of the gears.

3. In a motor, in combination with a shaft and a thrust bearing at oneend of said shaft, driving means-engaging said end of the shaft, force`feed lubricating means for .said motor, an abutment adjacent the end ofthe shaft opposite to that at which the thrust bearing is situated andmeans to admit oil under pressure fromy said lubricating means -to thespace between lsaid abutment and the adjacent end of said shaft to,thereby resist the end -thrust at the otherend of said shaft.
